IMPROVED ARTIPIGIAL FUEL.

KNOW ALL MENBY THESE PRESENTS: p

That we, A. W. BUCKLAND and A. M. mamas, both of the city and county of Hartford, and State of Con nee'tieut, have invented a certain new, useful, and improved Artificial Fuel; and we do hereby declare that the following is a full, clear, and exact description of the same.

Many different kinds of artificial fuel have been tried,but when put to a practical test they are found more or less objectionable.

A Some scent up the building while being burnt or consumed, while others require operations in the com pounding or preparation, which subject the operators and the buildings in which the operations are performed to the danger of explosions.

Our'present invention is designed to,obviatc in a great measure the foregoing and other objections.

The mode of compounding or preparing our improved artificial fuel from the articles or substances, and in the proportions substantially as hereafter named, is as follows:

A composition is first made of the following substances, and in about the proportions named, to wit';

Rosin, twelve pounds; gasoline, one gallon; sulphur, one ounce.

The mode of preparing the same is to put the rosin in aiLsuit-able vessel or kettle, the rosin being first broken up. The gasoline is now poured in upon the rosin, and both stirred occasionally, until the rosin has been properly cut by the gasoline, which will be eifected in the cour'seof thirty-six hours, depending much, however, upon the fineness of the rosin and the frequency of the stirring operation.

After the gasoline has properly cut and combined with the resin, the mucilage or liquid substance thus produced is dipped ofi' into a mixing-vat, tub, or box, and the sulphur added, and stirred in, after which a sumcient quantity of woody matter, such as saw-dust, shavings, or other similar materials, is mixed in to take up and absorb the liquid or mucilaginous substance, so as to prevent leaching or running thereof whenthe sub stance is removed to be caked or moulded.

- Before the compound is removed to be'caked or moulded, coal-dust is mixed in, in greater or less proportions, as may be desired, to give color, and also to add to the intensity of the heat when the fuel is burnt. I

The compound is then shovelled into moulds, of any desired shape, and allowed to remain until, the cakes harden sufiiciently to behandlcd, which, under ordinary circumstances, will be in about sin hours after the moulds are filled.

If the cakes are subjected to some little pressure, when the moulds are first filled, they can be removed from the moulds in a much less time, and if the compound is. allowed to remain in the mixing-vat or tub after being prepared, say from six to twelve hours, the caking operation will be greatly facilitated.

For cutting the rosin, any of the extracts of petroleum may be employed, but we prefer gasoline.

Our artificial fuel can ,be prepared in cold weather, and without the employment of artificial heat, thus rendering the operation safe and economical.

Having described the mode of making our improved fuel, what we claim as our invention, and desire to secure by Letters Patent, is p An artificial fuel made from the materials, in the proportions,-and i n the manner substantially as above described.- 4
